Converting to salt -- numbers seem high

Hey all,

I'm looking to convert my pool from chlorine to SWG this weekend. I've been taking data just to make sure that I get the reps in with testing before making the switch. I've noticed a weird pattern with my salt levels, which seems to be a large fluctuation. This pool has been maintained by a company until last Wednesday. That salt amount seems really high for not having a SWG on or adding any salt manually, no? Or does that not matter?


Also, ignore my CYA from June 30th -- I did the test wrong there 😬😬😬😬

Salt results are definitely suspect. You’ll need to know what you really have in order to set the correct level for a SWG. What are you using to test for salt?
 
How are you testing salt? The Taylor K-1766 kit is a good salt test kit. I find it to be one of the most consistent of all the tests. The variability of your salt test results indicate something may be wrong with the testing. Normally, higher salt levels can occur in non-salt pools due to salt being created from chlorine additions over time. Your level seems suspect since your signature indicates your pool was resurfaced two months ago. I wouldn't think it could build to your levels in that short of time.

Everything they've added to the pool adds salt but nobody tests their levels, ever, when using liquid chlorine or pucks.

It just goes to show you how ignorant the salt pool nay-sayers are. Your salinity is already there but they'll say a salt pool will cause corrosion and/or wreck your patio. :roll:

+1 to getting your true baseline with a K1766. The digital testers such as the pool store or the SWG system use conductivity and it can be off from other metals in the water and also water temp.
 
Then you had a 'salt pool' all along, or at least for a while now. Eye opening, isn't it ?
 
Help us out next time a TX pool builder is telling the newb how a salt pool is so terrible. 😁

This is an excerpt from Taylor's instruction card:

Rinse and fill 25 mL sample tube (#9198) to 10 mL mark with water to be tested.

A lot of folks stop reading after 25 mL...lol

I used a sharpie over that part of the instructions to just say "10 mL."
It's written in such a weird way that it would trip me up at least once a season.

I repeat '10 ml' from the second I pick up the vial until the drop of chromate hits.

10ml 10ml 10ml 10ml 10ml 10ml 10ml 10ml *drop*. PHEW. :ROFLMAO:

Oh boy. I logged another test today for all my numbers, but salt specifically was 1200. I definitely, definitely, definitely, did it to the 10 ml line. I'm thinking maybe I did the other ones wrong. That seems more likely than me having a ton of salt in my pool already? But I'm not totally sure at this point.
 
Most all pool chemicals add salt as a by-product. All chlorine pools will have measurable salt; some as high or higher than a "salt water" pool. It's what makes the pool industry FUD about SWCG so infuriating.
